With a rating of 8.5 on MohsScale of mineral hardness where hard steel gains 8 and diamond gets 10 it can be assumed to be the hardest material for the edge of any knife, needless a kitchen knife ever. It is made of zirconia or zirconium dioxide by dry pressing the zirconia powder and then firing and heating them by solid-state sintering method. It is known to have an edge retaining ability for a lifetime and rarely needs to be sharpened. Magnesium and calcium are often added to pure zirconia during its phase change process at high temperatures and minimize the change in volume which is responsible for stress fractures in pure zirconia. Characteristics Being made of not steel variants it is resistant to corrosion and rust thereby allowing it to be more robust and rugged in usage. It does not need intensive care like lubrication and maintenance like steel Ceramic Knives to protect them from rusting. Pressed zirconia is also chemically inactive to a lot of acids and bases and thus prevents it from discoloration and mixing with the food items while slicing and preparing them. They are heavy than their steel counterparts. Not only they can avoid corrosion at harsh environments but also they are non-magnetic and self-insulated, that is they do not conduct electricity and thus protects you from shocks while working with electric appliances like microwaves et cetera. They are the most suitable culinary tools for slicing boneless meat, vegetables, fruits and bread. However they are hard but are brittle as well which means that they cannot work on hard substances just like disjointing or cutting through bones of a chicken, frozen foods or in other instances which needs chipping across hard materials. They must be handled carefully because if dropped by mistake on a hard surface they are sure to break. But nowadays several vendors provide a new kind manufactured by HIP (hot isostatic pressing) which makes them black in color and provides additional toughness to it. Distribution These are primarily Korean made and are distributed in US through subsidiaries. They are cheaper as compared to the hardened steel knives of similar size and feature available in the market. Nowadays you can even find chefs using these because of their high performance. Manufacturing The procedure is a combination of age old techniques along with a taste of modernization. The raw materials, mentioned above, and water are mixed together in a cement mixer like drum to create a uniform composition throughout. Uniformity decides hardness of the blade. This liquid mixture is poured on a flat surface and allowed to cool until remains a fine powder. This is now poured into the mold of a Ceramic Knives and dry pressed at 10,000 psi until it turn hard and forms the blade of the knife. It is then removed from the mold and fired in a kiln at about 1400 degrees celsius. This is similar to the old technique of firing but with modern technology a more controlled temperature is maintained throughout the process. During this time the blade shrinks to about 1/4th of its original size and becomes hard and super dense compared to its initial state. As it has 8.0 rating diamond coated wheel is used to sharpen its edge and finally attached with a handle. In the market low and high grade look alike. The harder the material the sharper it can be made and all of this depends on just two factors- pressure and heat.
